Why does flux flow through ferromagnetic materials?

Click For Summary
SUMMARY

Magnetic flux flows through ferromagnetic materials, such as iron, due to their high permeability, which allows them to channel magnetic field lines effectively. In a toroidal configuration with a wire wrapped around it, the magnetic flux that penetrates one loop of the wire also penetrates all other loops due to the uniformity of the magnetic field within the toroid. This phenomenon is further illustrated by the behavior of a permanent magnet falling through a copper pipe, where induced currents create opposing magnetic fields that affect the magnet's motion.

Can anyone help me understand why magnetic flux flows through ferromagnetic materials like an iron ring?

Also, say you have a toroid with a wire wrapped around it (in air) how can you say that the flux that goes through one "loop" will go through ALL the others?

These are just some things my book didn't do a very good job on explaining.

By flux you mean how much of the field is going through the cross sectional area ?
Flux will flow through any conductor , like when i drop a strong permanent magnet down a copper pipe , it will reach a terminal velocity , because the field of the magnet starts current to flow in the pipe and creates its own B field that opposes the magnet.
If this is what you are talking about .
